7. With the Safety Trigger open, slowly open the
Abrasive Control Valve (19B) until abrasive
material begins to flow out of the Safety Trigger.
8. Adjust the Abrasive Control Valve (19B) until the
desired amount of abrasive material is flowing
through the Safety Trigger.
9. Begin blasting.
To Stop Blasting
1. While continuing to press and hold the Safety
Trigger, turn the Abrasive Control Valve (19B) to
the closed position (this is to prevent any
clogging.)
2. When you notice only air (no abrasive) is
coming out of the Safety Trigger, you can stop
the air flow by releasing the trigger. By doing
this you are ensuring a clean and clog-free
manifold, hose, and safety trigger.
Releasing Pressure from the Tank
1. When finished blasting, point Safety Trigger in a
safe direction away from people, pets or
anything around you that may be damaged by
direct or indirect abrasive spray.
2. Press and hold the Safety Trigger to expel any
remaining abrasive material from the Abrasive
Hose (25).
3. Close the Abrasive Control Valve (19B).
4. Release pressure on the Safety Trigger.
5. Close the Throttling Valve (19A) and the Air
Supply Valve (19).
6. Disconnect air supply hose from abrasive blaster.
7. Press the Safety Trigger until air stops flowing
and Pressure Gauge (16) reads "0".
MAINTENANCE
1. Keep your abrasive blaster clean, and protect it
from damage.
2. Release pressure from the tank after each use.
3. When initially pressurizing, check for leaks at
the tank top and at all hoses and fittings.
Leaking joints may be repaired by replacing
worn or damaged parts and Teflon tape at joints.
4. Check for worn abrasive hose and fittings. The
Abrasive Control Valve, manifold, and all parts after
the abrasive is ejected from the tank are subject to
rapid wear due to the flow of abrasive. Watch
especially for leaks, blistering, bulging or thinness
of the hose. Replace any parts which appear worn.
ABRASIVE SELECTION
The kind of abrasive you choose will greatly influence
the amount of time needed to clean a given surface
area. Abrasive materials include garnet, glass beads
and others. For best results, use 80 grit abrasive or
finer. Do not exceed 80 grit media size.
Abrasive Media Quick Reference Guide
Red Garnet
Hardness: 8
Red Garnet is good for general metal usage.
Ideal for general rust, paint and scale removal
from metal parts.
Glass Bead
Hardness: 6
Perfect for light deburring or applying satin-like
finishes on parts. Round shape of glass bead
keeps it from cutting into work surfaces; instead
the surface is pounded or "peened."
•
Make sure that the abrasive you use is
thoroughly dry. Damp abrasive can cause
clogging of your abrasive blaster.
•
While you may reuse abrasive, remember that
abrasive does wear out. After use, abrasive
becomes smoother and rounder, thus reducing
abrasive effectiveness.
•
Reusing abrasive may also cause clogging due
to debris contained in the mixture from prior use.
Abrasive Flow Adjustment
•
Choose a larger nozzle for a broader spray
pattern. Choose a smaller nozzle for more
focused abrasive blasting.
•
Adjust air pressure with the Brass Throttling
Valve (19A). Adjust abrasive flow with Abrasive
Control Valve (19B).
•
Watch for abrasive clogging. Release pressure
from the tank if necessary and replace the
abrasive with drier or cleaner abrasive.
Safety and Health Considerations
! WARNING: THIS MACHINE IS NOT
INTENDED FOR USE WITH SILICA
BASED ABRASIVES. SILICA BASED
ABRASIVES HAVE BEEN LINKED TO
SEVERE RESPIRATORY DISEASE.
ALWAYS USE SILICA SUBSTITUTES
(SUCH AS - GLASS BEAD OR RED
GARNET) WHEN ABRASIVE BLASTING!
•
Before opening tank make sure that it is not
pressurized. Be sure that the gauge reads "0".
If the gauge does not read "0", release pressure
from the tank (see "Releasing Pressure from the
Tank" section).
•
Disconnect the compressor before opening tank.
•
Protect yourself and those around you from
"over-spray". Remember that your portable
abrasive blaster is shooting a powerful spray of
abrasive material. Do not point it at yourself or
anyone around you.
